That's part of why I think this is relevant, the mix of stuff that showed up is a mix of:
- Stuff we knew was coming to Steam at some point
- Stuff we knew that's coming to PC at some point, but no Steam announcement
- Stuff that could conceivably be coming to Steam
- Stuff that's not announced but could easily be a plausible product
- Totally out to lunch stuff like Halo 3 and KOF that would be totally out to left field if they came to Steam.
